In Cuba September 27, 1937 v 3 Claims.

This invention refers to metal safety bars for doors, and it hasA forits object to provide means whereby the door safety bar is associatedwith the door lock-bolt so that the connection of the bar and itslocking pin will follow the lock-bolt in all the positions thereof uponopening and closing the door and upon the lock-bolt being in the safetyclosing position, whereby is obtained a more eflicient protectionagainst violations of doors as wheneverthe door is closed by thelockbolt the bar will be secured in locked position and can not bewithdrawn by violation.

The invention is described with reference to the figures of theaccompanying drawing, of Y which:

Fig. l is a partial front elevation of a door embodying the safety barforming the subjectmatter of this invention, in its locking position.

Fig. 2 is a horizontal section on line 2--2 of Fig 1.

Fig. 3 is a view similar to that of Fig. 1, with certain portions cutaway, showing the safety bar in its unlocking position.

Fig. 4 is a vertical section on line 4-4 of Fig. l.

Fig. 5 is a vertical section on line 5-5 of Fig. 1.

Fig. 6 is a detailed view showing the angular rod for connecting the barwith the lock bolt.

Fig. 7 is a horizontal detailed section on line 1 1 of Fig. 1.

Fig. 8 is a detailed View showing a modified form of connection of theangular rod of Fig. 6 with the lock bolt.

In the drawing, I indicates a door mounted by hinges 2 on a side offrame 3, and 4 indicates a lock fixed on the door I, and 5 is the lockbolt which is adapted to be introduced in a keeper 1 fixed to the otherside of frame 3.

The improvement constituting the subjectmatter of this inventionconsists in a metal bar preferably of square transversal section 8 whichhas one of its ends permanently connected by means of a union permittingits movement in vertical and horizontal planes, to the side of the frame3 on which the door-leaf I is hinged. Said union consists in a verticalpin 9 which passes through the bar 8 and is mounted through openingsformed in the upper and lower branches of a fork-shaped metal piece Iwhich is rotatably secured to a frame side 3 through a horizontaljournal II provided with a retaining head II' and mounted through anopening I2 formed in a metal plate I3 embedded in vertical position inthe fore face of the side of frame 3 and fixed by screws I4, a recess- Ibeing formed in the fra-me for receiving the head of journal II. Thevertical pin 9 is held in position by a head I6 with which it isprovided at one end and by a nut I1 threaded on the threaded surface ofits other end and secured by a cotter-pin I8 mounted across an openingthrough pin 9.

The free end of bar 8 has a horn-shaped opening I9 therethroughY withits wider end` backwards, to readily t a horizontal locking pin 20having on its free end a curved surface 20 to facilitate the insertionof the opening I9 of bar 8 on said pinY 20, the latter being integralwith a vertical plate 2I fixed by'screws 22 on the fore face of theVside of frame3 carrying the keeper 1, and the position of said lockingpin 2D being such that it remains in horizontal alignment with thevjournal II above described. The pin 20 has near its free endahorizontal transverse perforation 23 adapted to v'receive the end of anL-shaped rod 24 slidably mounted on the fore face of the bar 8 throughthe medium of guides 25 fixed to the bar and provided with openingswherethrough passes the longest portion of the L-shaped rod 24, and theshortest portion of this L-shaped rod 24 is detachably connected withthe lock-bolt 5 of lock 4 by means of a fixed stop 26 secured to thebolt 5 and a horizontal pin 21 provided with a stop head 28 and whichpasses through an opening formed in the bolt 5, said pin 21 beingslidable forwards and backwards from the bolt 5 against the resiliencyof a spring 21 rolled about the portion of pin 21 remaining behind thebolt 5 and having its ends resting respectively on the rear face of bolt5 and on a collar 30 fixed at the rear end of pin 21.

In its horizontal position, the bar 8 rests at its lower edge on anangular plate 3| fixed by screws on the face of door I adjacent the bar8, and the latter is also retained in its safety position by a verticalclamp 32 rotatably mounted by a horizontal pivot 33 on the free end of aZ-shaped plate 34 which at its other end is secured by screws 35 totheface of door I adjacent the bar 8.

The length of the longest portion of the L- shaped rod 24 is such thatin the closed position of the bolt 5, that is, when the end of thelatter is introduced in the keeper 1, the free end of said L-shaped rod24 is introduced in the horizontal opening 23 of the locking pin 2U (seeFigs. l and 2 of the drawing), in which position, when the ordinarysafety means is applied to the bolt 5 of lock 4, the bar 8 will also besafely secured, thereby preventing disconnection of the L- shaped rod 24from the pin 20 fixed to the frame 3 of the door.

When the lock 4 is operated by the respective key from the outside or bythe handle 6 from the inside, upon the bolt 5 being caused to withdrawfrom the staple 1, the L-shaped rod 24 will also slide and disengage theopening 23 of locln'ng pin 20, and whenever the door l is closed againstframe 3, the L-shaped rod 24 will enter the opening 23 of locking pin 20at the same time that the bolt 5 enters the keeper '1.

When it be desired to Withdraw the bar 8 from the position in which itlocks the door I, it will be sufcient to rotate the bar 8 forewards todisengage the horn-shaped opening I9 from the locking pin 2U, afterhaving disconnected the L-shaped rod 24 from the bolt 5, and by causingthe clamp 32 to rotate upwards, it will then be possible to cause thebar 8 to rotate together with the fork l0 on the horizontal journal Il,to take the vertical dropping position indicated by dotted lines in Fig.1 of the drawing.

In Fig. 8 is indicated a modified form of the means for connecting theL-shaped rod .24 with the bolt 5, the above described fixed stop 26 andslidable pin 21 being replaced by a resilient forkshaped clamp 36 xed bya rivet 3l to the bolt 6. For disconnecting the L-shaped rod 24 from theresilient fork 36, it is only necessary to cause the longest portion ofthe L-shaped rod 24 to rotate in its guide pieces 25 and to pullforewards the shortest portion of the rod 24 to withdraw it from theinterior of resilient clamp 36.

Thebar 8 may be provided near its connection with fork` I 0 Awith aplurality of drill holes 38 each of 'them being adapted to receive thevertical'pin 9, the length of the bar 8 being thus adaptable todoorsofdifferent width, by cutting the bar 8 beyond the hole 38 to be used.

This bar 8 is adaptable to doors of any kind, or of one or more leaves,and to any kind of locks.

What I claim is:

1. A metal safety bar for doors, in combination with a locking-pinsecured t0 the door. frame, the bar having at one end thereof means forconnecting it with the door-frame which permit its rotation in twoperpendicular planes, and means slidably mounted on the other end of thebar, said means being connected to the bolt of a door lock and adaptedto be detachably connected to the locking-pin, so that the latter meansmayautomatically follow all of the movements of the lock bolt.

2. A metal' safety bar for doors, in combi-nation with a locking-pinsecured to the door frame,

the bar having at one end thereof means for connectingit with the doorframe, which permit its rotation in two planes one vertical and anotherhorizontal, and an L-shaped rod slidably mounted in guides xed to thebar, which L-shape rod has a portion thereof detachably connected to thebolt of a door lock and the other portion thereof being adapted toengage the locking pin in its locking position.

3. A metal safety bar for'doors, in combination with a perforatedlocking-pin secured to the door frame, the bar having at one end thereofmeans for connecting it with the door frame which permit its rotation intwo planes, one vertical and another horizontal, and an L-shaped rodslidably mounted in guides fixed to the bar body which- L-shaped rod hasits shorter portion detachably connected with the bolt of a door lockVand its longer portion adapted to be inserted in the perforation of thelocking pin in its locking position. v
